In response to the intensified and widespread impacts of climate change to the economy and society and in recognition of the imperative to manage and reduce greenhouse gas emissions in Thailand, the Thailand Greenhouse Gas Management Organization or TGO was established in 2007 as an autonomous public organization in accordance with Thai law to manage and expedite development and implementation of greenhouse gas reduction projects and support public, private and international organization partnerships to promote implementation of climate action.

The Royal Decree on the Establishment of TGO B.E. 2550 was amended in 2019 to strengthen the efficiency and effectiveness of TGO in carrying its missions and mandate to support greenhouse gas management in Thailand in line with evolving international climate change regime, as well as accommodating the amended Public Organization Act B.E. 2542 (amended B.E. 2550).
